Ionic liquid anchored to silica (nano-SB-[PSIM]Cl): a highly efficient nanocatalyst for the solvent-free preparation of 1-thioamidolakyl-2-naphthols
Journal Title: Eurasian Chemical Communications - Year 2019, Vol 1, Issue 0
Abstract
Nano-silica-bonded 3-n-propyl-1-sulfonic acid imidazolium chloride (nano-SB-[PSIM]Cl) was applied as a highly efficient, general and heterogeneous catalyst for one pot multi-component reaction of 2-naphthol, arylaldehydes, and thioacetamide leading to 1-thioamidolakyl-2-naphthols. All reactions proceeded with excellent yields in short times under solvent-free conditions. Our protocol was superior than most of the reported methods for the preparation of 1-thioamidolakyl-2-naphthols in terms some factors included relatively short reaction times, moderate to high yields, and absence of organic solvents.
